<ul type="square">

<li><u>In general, give at least 5 decimal places.</u>
<blockquote>Typically, if your answer is correct to 5 decimal places it will be marked correct, although the number of decimal places required may vary from problem to problem.  When in doubt, give more decimal places.</blockquote>
</li>

<li><u>If there is more than one correct answer, enter your answers as a comma separated list.</u>
<blockquote>
For example, if your answers are <nobr><tt>-3/2, 4/3, 2pi, e^3, 5</tt></nobr> enter them as
<nobr><tt>-1.5, 1.3333333, 6.2831853, 20.0855369, 5</tt></nobr>
</blockquote>

<li><u>Sometimes, fractions and certain operations are not allowed.</u>
<blockquote>Usually, the operations that are not allowed include addition <tt>+</tt>, subtraction <tt>-</tt>, multiplication <tt>*</tt>, division <tt>/</tt>, and exponentiation <tt>^</tt> (or <tt>**</tt>).  When these operations are not allowed, it is usually because you are expected to be able to simplify your answer, often without using a calculator.</blockquote>
</li>

<li><u>Sometimes, certain functions are not allowed.</u>  
<blockquote>Usually, the functions that are not allowed include square root <tt>sqrt( )</tt>, absolute value <tt>| |</tt> (or <tt>abs( )</tt>), as well as other named functions such as <tt>sin( )</tt>, <tt>ln( )</tt>, etc.  When these functions are not allowed, it is usually because you are expected to be able to simplify your answer, often without using a calculator.</blockquote>
